PASTING APPARATUS FR CGARETTE-MAKING MACHINES.

Application filed January 7, 1915.

To all whom t may concern.'

Be it known that l, MAX CLnMnNs Guerin, a citizen ot' the German Empire, and residing at Dresden-Loebtau, in the German Empire, have invented a new and useful improvement in Fasting Apparatus for Cigarette-Making Machines, of which the following is a full and clear specifica tion.

The invention relates to a pasting apparatus for cigarette-making machines, in

which a moving and flat strip of cigaretteV paper is provided with paste on one of its long edges, so that when the strip of cigarette paper is shaped to form to a round sleeve, the longitudinal edges of the strip are pasted toget-her. Such forms of pasting apparatus are already known. They all have pasting disks, which revolve in a vertical plane and project into a container having pasting material.

The pasting apparatus according to the present invention has a container for the pasting material movably mounted, and the pasting disk is arranged so as to dip into the paste of the container. The paste con-` tainer is also provided with a cover, and the entire pasting apparatus is movable as a unit.

An advantageous embodiment of my invention is set forth in the following descrip` tion and drawings in whichh VFigure l is a side-view in partial section.

Fig. 2 is a top-view.

F ig. 3 is a special view showing details or" the construction which enables the uncover` ing of the pasting disk and of the pastecontainer (it is a cross section on line 3 8 of F ig. l in the direction of the arrow). F ig. fi is a special view of the arrangement for puttingthe pasting apparatus into oper'- ative position and is a cross section on line 1 -4 of F ig. 1 in the direction of the arrow.

The pasting disk a is mounted on a horizontal shaft b which is mounted in the vertical wall A of the trame of the pasting apparatus. On the other end of this shaft is a toothed wheel o by means of which the pasting disk a is revolved in the direction of the arrow shown in Fig. l.

The pasting disk dips into the container B for the pasting material, through the front side thereof through a vertical slit. Because of the dipping in, the pasting disk a comes in touch with the pasting material found in the container B, in such a manner Specification of Letters Patent.

that the edge el of the pasting disk is covered with a layer of the pasting material. Above this edge Z the strip of cigarette paper t) is led. rlhis strip of cigarette paper C is indicated by dotted lines in ldigs. l and The strip of cigarette paper C lies tiat and in such relation to the pastingdisk that one longitudinal edge of the strip C is provided with pasting material. The strip ot oigarette paper C moves iorward in the direction of the arrow shown in Fig. 1.

The pasting material is thus applied equally and in desired strength upon the edge of the pasting disk a.. rlhis can be readily regulated in the pasting apparatus, because the pasting disk a dips into the container for the pasting material B from the front. To regulate the amount of the pasting material on the edge d of the pasting disk a: the lower edge e of the slit in this front side is approached more or less to the edge of the pasting disk a.. The pasting material remaining clinging to the sides of the disk t will thus be stripped oi by the side edges of the slit in the container B. As these side edges are inclined, corresponding to the conical shape of the disk a, they always fit tightly against the sides of the pasting disk a during the lifting and loweru ing of the container B.

rlhe container B for the pasting materia-l forms a part of a lever which is revoluble in a vertical plane on the horizontal t'rame bolt j. By means of this revolution around the bolt f the edge e of the slit can be moved with respect to the pasting disk a. In order to exactly regulate the relative position between the edge e and disk a, the position screw g is provided. This is at the iti-ont end of a pin t fastened to the bottom of the container B. rlhe pin it. forms the free end of the lever revolving on the bolt f. The position screw g reacts against the projection a' of the wall A of the frame. The turning of the screw g results in the rising and lowering of the container for the pasting material.

ln order to bring the container B of the pasting material entirely out of engagement with the pasting disk a, the arm 7L is made revoluble in a horizontal plane, namely upon the vertical bolt 7c upon the bottom of the container B for the pasting material. lf the arm t is swung away from the wall A of the trame, then the container B can be moved below, until it is perfectly free. This is often necessary for the purposes of cleaning and the like.

The strip of cigarette paper C runs, as already said, above the top of the pasting roller in order to receive paste on one of its longitudinal edges.

This delicate silk cigarette paper' strip, in some cases, tears in the very quickly moving cigarette makingmachine. 1f such a tearing of the strip occurs, the fluttering ends of the strip may fall at the place of breaking upon the pasting roller and upon the container for the pasting material. 1n particular the end of the strip can twist and wind upon the pasting disk a. In this manner the strip of paper C would be soiled with paste, and a long and disagreeable delay would occur. In order to avoid this evil, the pasting apparatus, according to the invention, is provided with a horizontal cover-plate D, which lies at some distance from the stretched strip of cigarette paper. This covering-plate D prevents the torn strip of cigarette paper from falling down upon the pasting disk or the container of the pasting material. The pasting disk L projects through a slit Z of the covering plate D. Upon the covering plate is a bearing .El tightened by means of screvs which carries a coperating disk a', for the pasting disk a. Between the cooperating disk a and the pasting disk a the longitudinal edge of the strip of cigarette paper C that is to be covered with paste is led. This cooperating disk a is only necessary, when the strip of cigarette paper is provided with mouth pieces of straw or similar brittle material, because the strip of cigarette paper may be bent and stretched at the place of covering. The covering plate D is revoluble in a vertical plane. Tt can revolve about the bolt m resting in the wall A of the frame. Tt has a projection n beyond the point of revolution m which projection is provided with a horizontal boring 0. 1n this boring 0 the pin p is located, and the pin is longitudinally movable therein. This pin has on its front end a cone f] and a pin projection r. 1n the wall A of the frame a corresponding boring s is provided. As long as the pin y? only projects in the boring s of the wall of the frame with its projection o, the covering plate D lies in its normal position as shown in Fig. 1. As soon, however, as the pin is pushed forward to the wall of the frame, the cone y through its action with the edge of the boring s of the wall of the frame causes a lifting of the covering plate D to a small amount. This lifting of the covering plate D raises the strip of cigarette paper from the edge of the pasting disk a. The lifting of the strip of cigarette paper is especially necessary when a new strip is to be lcd into the machine or a torn strip is to be threaded in. In this case, it is highly unde- The pasting apparatus which is mounted on the wall A of the frame is mounted mov ably as a unit in the frame E of the machine. 1n order to attain this, the plate of the frame is placed on two horizontal bolts F and 'Qr fastened upon the frame E'of the machine. The pasting apparatus rests inovably upon these bolts so that it can Ybe approached or withdrawn from the frame E of the machine. This movability is necessaryin order to always place the edge d of the pasting disk a so exactly that it coincides with the outer longitudinal edge of the strip of cigarette paper'. As the width of the strip of cigarette paper changes (being dependent upon the diameter of the cigarettes manufactured at that time), but the position of the edge to be provided with pasting mate-V rial always remains the same.y the pasting disk must therefore be placed in the proper position. In order to secure this positioning of the pasting disk most accurately and to fasten the pasting apparatus in the proper position, the following arrangement is provided.

Around the boltrG a spring H is wound which presses on one side thereof against the frame E of the machine and on the other side thereof against the wall A of the fra-Ine of the pasting apparatus and presses this wall against a ledge or abutment t. The ledge t is movable. 1t consists of the head t of a spiral screw u that is screwed into a corresponding boring of the pin G provided with inner screw threading. The position of the ledge t changes according to the amount which the spiral screw u is screwed into the boring of the pin G. In order to fasten the spiral screw in the desired position, it is hollow and longitudinally slitted, so that two elastic legs are produced. 1n the hollow of the pin a special spindle is arranged which can be tightened or loosened by means of a screw 10. The spindle is provided with a cone a@ which rests against a correspondingV depression on the front end of the spiral screw. Upon the tightening of the screw u', it therefore forces apart the spiralV screw so that it is fastened by friction in the boring of the bolt G which is provided with coperating threads. In this manner an exact positioning and a secure fixing of the pasting apparatus in the desired positionV is possible.

Between the ledge z5 and that part of the wall A of the frame which is movable upon the bolt G an intermediate member y is placed. The intermediate member consists of a lever provided with a handle which lies with a recess .e above the spiral screw u. The lever is revolubly fastened to the wall of the frame A. If, however, the lever is lifted upwardly from the spiral screw u, then the frame glides forwardly till it strikes against 15. This gliding is suliicient to bring the edge CZ of the pasting disk a out of contact with the strip of cigarette paper. The pasting disk a can be separated from the strip of cigarette paper by raising the lever y, as well as by raising the covering plate D.

A doctor J is provided which can be temporarily pressed against the wall of the pasting disk a in order to scratch off the pasting material dried there.

I have mentioned one embodiment of my invention, but it is clear that numerous changes could be made in the detail without departure from the spirit thereof.
